Im having the same issue;
So I bought the game yesterday, Installed from he disc, when i tried to launch the game nothing happens. steam dialog pops up telling me the game is being launched, the computer thinks for a sec, and then nothing.
I have a widescreen monitor so i tried to change its start up resolution, but there are no files in my script folder.
Then I installed downloading from steam, same thing happens.
The game doesn't not even load the title screen.
Is there anything i put in the launch option to start it windowed? but it doesn't look like its a resolution problem mainly becasue the engine doesn't initialize. The screen doest flicker to switch over to a full screen app or anything.
